hive 1.1 take out hierarchy value from three tables
I have the following tables in HIVE (1.1 version) and need the output as shown in the Result. As UNION is not available in hive 1.1, need different approach to get the below result.
Table A:
id name
1 One
2 Two
4 Four
Table B:
id name
1 ONE
3 THREE
4 FOUR
Table C:
id name
1 one
2 two
3 three
5 five
Result
id name
1 One
2 Two
3 THREE
4 Four
5 five
